Summary
Magnetic resonance-guided microwave ablation is a feasible and effective treatment for lung malignant tumors. This technique shows promise for evaluating treatment efficacy with minimal complications.
Area of Science:
- Oncology
- Radiology
- Minimally Invasive Procedures
Background:
- Lung malignant tumors pose a significant treatment challenge.
- Minimally invasive techniques are increasingly preferred for tumor ablation.
- Magnetic resonance imaging (MRI) offers precise guidance for interventional procedures.
Purpose of the Study:
- To evaluate the feasibility and efficacy of MRI-guided microwave ablation (MWA) for lung malignant tumors.
- To assess the safety and effectiveness of this novel approach in a single center.
Main Methods:
- Prospective investigation of 22 patients with 23 malignant lung tumors.
- Percutaneous MWA guided by 1.5T MRI using a MR-compatible microwave antenna.
- Intraoperative monitoring of ablation zones and post-procedure follow-up.
Main Results:
- Successful treatment in all patients with an average operation time of 72.21 minutes.
- MRI demonstrated changes in lesion signal intensity during ablation.
- High technical efficacy of 95.5% with no serious complications reported.
- Average follow-up of 12.89 months with one local recurrence.
Conclusions:
- MRI-guided MWA is a feasible and effective treatment for lung malignant tumors.
- This technique offers unique advantages for efficacy evaluation.
- The procedure is safe and well-tolerated by patients.
